Name 4 Major Tissue Types
|
Epithelial Tissue (ET)
Connective Tissue (CT) Muscle Tissue (MT) Nervous Tissue (NT) |
|
|
Name the 4 major characteristics of Epithelial Tissue (ET)
|
Polarity
Cellularity Has basement membrane Avascular |
|
|
Polarity
|
Major Characteristic of Epithelial Tissue (ET)
Faces a free surface such as, lumen (cells are exposed to a cavity) |
|
|
Cellularity
|
Major Characteristic of Epithelial Tissue (ET)
No intercellular matrix (no space between the cell) |
|
|
Has basement membrane
|
Major Characteristic of Epithelial Tissue (ET)
supported by connective tissue - basement membrane - basal lamina - reticular fiber layer (lamina reticularis) |
|
|
Avascular
|
Major Characteristic of Epithelial Tissue (ET)
No direct blood supply |
|
|
Regeneration
|
Major Characteristic of Epithelial Tissue (ET)
High mitotic rate - these cells are constantly replacing themselves |
|
|
Name the 3 shapes of epithelial tissue
|
Squamous - flat
Cuboidal - cube or dice Columnar - taller than wide |
|
|
Name the 4 layers of epithelial tissue
|
Simple - one cell layer thick
Stratified - two or more cell layers Pseudostratified - all cells touch the basement membrane Transitional - specialized for stretching |
|
|
Goblet Cells
|
Produce mucus
Found in simple columnar epithelial tissue (Look like pineapples) |
|
|
Goblet Cells
|
Found in Simple Columnar ET
Produce mucus |
|
|
keratinized
|
Found in Keratinized Stratified Squamous Epithelium
On dry surfaces (skin) protein to form a barrier to water, microbes, and abrasion |
|
|
nonkeratinized
|
Found in non-keratinized stratified squamous epithelium
On moist surfaces (mouth and vagina) - surface cells are living and there is less abrasion |
